When using gradient descent with projection at the command line, you can specify
whether the algorithm enforces the model initial conditions using hard or soft constraints
by specifying the ConstraintType option in findopOptions.
To specify the optimizer type in the:
- Steady State Manager, first open the Trim the model dialog box. On the
Specification tab, click Trim Options. Then, open the Options tab. - Linear Analysis Tool, first open the Trim the model dialog box. On the Linear
Analysis tab, in the Operating Point drop-down list, select Trim Model.
In the dialog box, in the Optimization Method drop-down list, select an optimizer.
When you use gradient descent with projection in the Steady State Manager or Linear
Analysis Tool, the algorithm enforces the model initial conditions using hard constraints.
For an example that uses projection-based trim optimization, see “Steady-State
Simulation with Projection-Based Trim Optimizer” on page 1-139.
